Sometime during the week between May 2, 2001 and May 9, 2001, something stirred the waters along the southern coast of Brazil. The SeaWiFS images from those days shoow the transition from blue water almost up to the coast on May 2, 2001 to turbid blue-green in a roughly 80 kilometer wide band on May 9, 2001. The metropolitan areas of Rio de Janeiro, São Paulo, and Belo Horizonte can be readily distinguished in the full-resolution images as whitish-gray splotches. Inland, the Parana River and its tributaries are clearly visible. Sensor: OrbView-2/SeaWiFS. Data Start Date: 5/2/01.
